The product arrived on time and in good shape. I had very little trouble assembling it and had it up within half an hour. Requires no tools and just snaps together. No problem. But the overall structure seemed slightly smaller than I imagined. And it was indeed a bit flimsy. I have two cats and they both immediately checked it out. Unfortunately, its flexible construction is really only suitable for small to average cats. Any cat over 15 lbs would be very uncomfortable. My chartreaux, for instance, at 23 lbs. is just too big for this thing. He attempted to climb onto the lowest hammock but found it too flimsy for comfort. He remained on the ground level and was bored with the whole thing within a few minutes. My smaller cat (10 lbs) found it a bit more enjoyable and carefully, if awkwardly, ascended all the way to the top--it was even a bit rickety for her. But again, like the other cat, she became bored within a few minutes and wanted out. I'm not sure it's worth the cost, in short. I'm not entirely disappointed I tried. But I think anyone contemplating this purchase should consider the size of their cats first. You should also trim your cats' claws. They can very easily get caught in the nylon cord that makes up the netting.
